MANUFACTURE OF SHACKLE-CLIPS.

SPECIFICATION forming part of Letters Patent No. 857,450, dated February 8, 1887.

Application filed July 6, 1886. Serial No. 207,206.

To aZZ whom it may concern:

Be it known that I, FRANK P. Barns, of Syracuse, in the county of Onondaga, in the State-0f New York, have invented new and useful Improvements in the Manufacture of Shackle-Clips for Vehicles, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention consists in a novel construction of a blank from which a clip adapted to be applied to an axle and provided with ears for attachment of the thills can be formed in an expeditious, inexpensive, and in a perfect manner; and the invention also consists in a novel construction of dies designed for forging or swaging the aforesaid blank, all as hereinafter more fully described, and specifically set forth in the claims.

Inthe annexed drawings, Figure 1 is a plan view of the blank. Fig. 2 is a side view of the same. Figs. 3 and 4 are face views of the two dies. Fig. 5 is a longitudinal section of the dies with the blank inclosed, taken on lines w 00, Figs. 3 and 4. Fig. 6 is a transverse section of the dies and inclosed blank, taken on line y 3 Figs. 3 and 4; and Fig. 7 is a side view of the clip complete.

Similar letters of reference indicate Sponding parts.

The blank is formed of wrought metal, and composed of a plate,P, a cylindrical shank, G, projecting from one end (designated the rear end) of said plate and nearly in the same plane therewith. The opposite end of the plate P is curved downward from the plane of the main portion of the plate, as shown at P, and this curved or deflected end is re-enforced by a cross-bar, P, from which project forward two ears, D D, and between said cars is a cylindrical shank, G, projecting forward fron the lower edge of the cross-bar P.

The described blank I forge or swage from a bar of wrought-iron or steel of proper size by means of the female die A and male die B receiving the heated metal bar between them,

and subjected to sufficient pressure or blows I to compel said bar to conform to the shape of the adjacent faces of the dies.

The female die A is formed with a recess,a, the outline of which corresponds to that of the bottoms and outer sides of the ears D D, and

(No model.)

the depth of the recess also corresponds to the depths of said ears. Said recess is made flaring toward the top, so as to allow the blank to be readily removed therefrom. In the bottom of the recess a, central of the width thereof, is

agroove, f, of the requisite dimensions to contain the metal which forms the lower half of the shank O of the blank. At the rear end of the recess a the die A is formed with an upward-projecting offset, 1), corresponding to the downwardly-curved end portion of the plate P of the blank, and back of this offset the top of the die A is formed with a smooth face, 0, the outline of which corresponds to that of the plate P, and from'the rear end of the face 0 is extended rearward a groove, 1', of a size to contain the metal forming the lower half of the shank C of the blank.

The male die B is formed at one end of its face with a boss, (I, which is tapered to correspond to the flare of the recess a of the female die, into which recess the boss (I enters. The boss is reduced in width and length, so as to form spaces at its sides and at the end adj acent to the offset 11 of the female die, said spaces corresponding to the thicknesses of the ears D D and crossbar P of the blank.

The under side or face of the boss (I is provided with a longitudinal groove, g, which coincides with the groove f in the female die, and with said groove forms the shank O of the blank. Back of the boss (I is a recess,e, formed in the die B, corresponding in outline to that of the smooth face a of the female die A, said recess being of a depth to form the plate P of the blank, and from the rear end of the recess e is extended rearward a groove, Z, which 00- incides with the groove '5 of the die A, and with said groove forms the shank G of the blank.

In forming the blank I properly heat a bar of steel or wrought-iron of suitable size and introduce it between the dies A and B, and then subject said dies to the requisite pressure or blows to drive the interposed hot metal into the cavities of the adjacent faces of the dies,

and thereby produce the blank represented in and B by subjecting the bar to an auxiliary break-down die for preliminary grading the bar approximately to size, thereby saving the finishing-die from undue wear and strain.

The described blank is readily converted into the clip by bending the plate Pinto U shape and bending the shank O downward, so as to stand nearly or quite parallel and directly in front of the shank O, as represented in Fig. 7 of the drawings.

The ears I) D are easily bent from their i11- clined positions to vertical and parallel positions.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. The female die A, formed with the recess a, flared toward the top, the offset 1) at the rear end of said recess, and the smooth face 0 back of the offset, in combination with the male die B, formed with the beveled boss (I, entering thcreccss a and having spaces at its sides and at the end adjacent to the offset 1), and providcd with the recess 0 back of the boss and over the face 0, substantially as described and shown.

2. The female die A, formed with the recess a, the groove fin the bottom of said recess, the offset 1) at the rear end of the recess a, and the smooth face 0 back of the offset, in combination with the male die B, formed with the boss (1, entering the recess a and having spaces at its sides and at the ends adjacent to the off set b, and having the groove 7, coinciding with face 0, in combination with the male die B, 4o

formed with the beveled boss (I, entering the recess a, and having spaces at its sides and at the end adjacent to the offset b, the groove 9, coinciding with the groove 1', the recess 6 back I of the boss, and the groove Z, coinciding with 5 the groove 13, substantially as described and shown.

4-. The within-described shackle-clip blank, composed of the plate 1?, the shank 0, projecting from one end of said plate, the ears I) 50 D, projecting from the opposite end of the plate I, and the shank G, projecting from the said plate between the ears D D, substantially as shown in Fig. 1 of the annexed drawings.

In testimony whereofI have herenntosigned 55 my name and affixed my seal, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 29th day of June, 1886.
